NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 597,324, dated January11, 1898.

Application filed April 16, 1897.

To all whom, it may concern.-

Be it known that I, JACOB PRYOR PECK, a citizen of the United States,residing at Sharon, in the county of W'eakley and State of Tennessee,have invented certain new and useful Improvements in Nut-Locks and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

' This invention relates to certain improvem cuts in nut-locks forrailroad rail-joints, the object being to provide in a simple andinexpensive manner a nut-lock which may be readily applied to secure thenuts ordinarily used.

A further object of the lock is to provide means whereby the fish-plate,should it become broken, may be retained in its position without dangerof displacement to the rails.

The invention comprises certain novel features of construction andarrangement of parts whereby the above and other important advantagesare attained, as will behereinafter fully described, and specificallydefined in the appended claims.

In the accompanying drawings, Figure 1 represents a perspective view ofthe ends of two adjacent rails fastened together by the ordinaryfish-plate and bolts and showing my improved nut-lock in positionthereon. Fig. 2 is an edge view, on an enlarged scale, removed from therails; and Fig. 3 is a plan view thereof.

Similar reference-numerals indicate corresponding parts in all figuresof the drawings.

1 1 represent the meeting ends of two adjacent rails. 2 is a fish-plate,and 3 the nuts used upon the ends of the bolts, which pass throughopenings in the fish-plates and the web of the rail in the ordinarymanner to secure the rail-sections together.

4 indicates my improved nut-lock, shown as a metallic platecorresponding in length to the length of the fishplate, the intermediateportion of which is provided with a lateral projection 5, in which asquare opening 6 is formed to receive within it the head of a spike 6,and the ends are formed with an offset 7 to provide shoulders 7, againstwhich the ends of the fish-plate will bear.

The ofisets 7 of the plate 4 are provided Serial No. 632,378. (Nomodel.)

with elongated openings 8,through which and openings formed in theflange of the rail suitable bolts 8 are passed, their lower extremitiesbeing slotted to receive the ordinary split pin, by which means theplate 4 is secured firmly to the Web of the rails.

The intermediate portion of the plate 4 is enlarged upon thelunder side,so that in applying my improved nut-lock the inner edge of the plate,which bears upon the face of the fish-plate, may be brought close upagainst the under side of the nuts 3, so that the rotation thereof tothe slightest degree will be absolutely prevented. The ofisets or endsadjacent to the ends of the fish-plate are broadened, so as to permit ofthe inner edge of the offiset coming close up to the web of the rail,

as clearly shown in the drawings.

The spike 6 is driven into the opening 6 and through the opening in theweb of the rail into the sleeper or cross-tie and serves to assist inretaining the plate 4 in its proper relative position therewith; butthis opening may not be considered necessary, and may therefore beentirely dispensed with, and the elongated opening 8 in the offset 7will provide for the ordinary expansion and contrac- I tion of the rail.

Should the intermediate under side of the plate 4 be so large as toprevent the offsets from engaging with the web of the rail, the splitpins or other devices used to engage their slotted ends will serve todraw the offsets toward the web of the rail and thus give greatersecurity thereto.

It will thus be seed that my invention provides in an effective anddurable manner a nut-lock which may be readily and quickly applied torail-joints as at present constructed, and by reason of the shoulderslocated at the ends thereof the fish-plates, should they become brokenor otherwise injured, will be prevented from separating with the rar s.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. Aunt-lock, comprisinga plate having an enlarged intermediate portionprovided with an opening, shoulders arranged at each end of the plateand adapted to engage the ends dered ends and provided with openings,slotted boltsto engagezsaid' openings, and open receive bolts adapted topass through said openings and'openings in thefiange-of the rail, andmeans to retain said bolts in place, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
